La-Gly-VB_6对酸雨胁迫下玉米若干生理指标的影响

Influence of La-Gly-VB_6 on the Growth of Corn under the Acid Rain Stress

用30mg/LLa-Gly-VB6处理玉米幼苗一次,可减轻pH2.0酸雨对玉米造成的伤害。实验结果显示,此与La-Gly-VB6可提高玉米的光合速率,叶绿素含量和根系活力,减少丙二醛含量,降低质膜透性,维持细胞汁液pH值的稳定性,与硝酸还原酶及脱氢酶活性等多重生理生态效应相关。

Ecophysiological effect of La-Gly-VB6 on corn made by acid rain has been studied. When corn is sprayed with 30 mg/L La-Gly-VB6 once, the harmfulness to corn from acid rain pH2.0 will be reduced. The results indicate that this has something to do with many physiological effects, such as La-Gly-VB6 being able to speed up photosynthesis, root vigor and chlorophyll content, reduce malonic aldehyde content, decrease cell membrance permeability and keep the stability of cell juice pH value, and maintain the activity of NR and dehydrogenase in corn, etc.
